ABSTRACT:
The invention relates to a measuring window for a process refractometer. Process refractometers are commonly used in the industry for continuous measurement of the concentration of a solution. The wall of the refractometer facing the process solution is provided with a window which must satisfy the requirement that the passage of light rays satisfies certain criteria, that the sealing is reliable, that the fastening is firm and that the wall facing the process and the window form a planar surface. The transparent portion of the window according to the invention comprises a roof prism embedded in a V-shaped groove in the process wall. Each wall of the V-groove is provided with a sealing abutting against the prism, and the third side of the prism forms a continuous plane with the process wall.
